Dorylinae is an ant subfamily, with distributions in both the Old World and New World. Brady et al. (2014) synonymized the previous dorylomorph subfamilies under Dorylinae, while Borowiec (2016) reviewed and revised the genera, resurrecting many genera which had previously been merged. Dorylinae genera are suggested to have evolved sometime between 102 to 74 million years ago, subsequently undergoing rapid adaptive radiation events during their early history.
Adetomyrma is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species Adetomyrma venatrix was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae.
Amyrmex golbachi is a rare Neotropical species of ant and the only known species in the genus Amyrmex. It is currently only known from males from the Amazon basin of Brazil and from northern Argentina.
Nothomyrmecia, also known as the dinosaur ant or dawn ant, is an extremely rare genus of ants consisting of a single species, Nothomyrmecia macrops. These ants live in South Australia, nesting in old-growth mallee woodland and Eucalyptus woodland. The full distribution of Nothomyrmecia has never been assessed, and it is unknown how widespread the species truly is; its potential range may be wider if it does favour old-growth mallee woodland. Possible threats to its survival include habitat destruction and climate change. Nothomyrmecia is most active when it is cold because workers encounter fewer competitors and predators such as Camponotus and Iridomyrmex, and it also increases hunting success. Thus, the increase of temperature may prevent them from foraging and very few areas would be suitable for the ant to live in. As a result, the IUCN lists the ant as Critically Endangered.
Amblyopone is a genus of 10 species of ants, found in Australia, New Caledonia, New Guinea and New Zealand. Ants of this genus possess the gamergate, meaning workers are able to reproduce within a colony lacking a queen.
A gamergate is a mated worker ant that can reproduce sexually, i.e., lay fertilized eggs that will develop as females. In the vast majority of ant species, workers are sterile and gamergates are restricted to taxa where the workers have a functional sperm reservoir ('spermatheca'). In some species, gamergates reproduce in addition to winged queens, while in other species the queen caste has been completely replaced by gamergates. In gamergate species, all workers in a colony have similar reproductive potentials, but as a result of physical interactions, a dominance hierarchy is formed and only one or a few top-ranking workers can mate and produce eggs. Subsequently however, aggression is no longer needed as gamergates secrete chemical signals that inform the other workers of their reproductive status in the colony.
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant.
Agroecomyrmecinae is a subfamily of ants containing two extant and two fossil genera. The subfamily was originally classified in 1930 by Carpenter as Agroecomyrmecini, a Myrmicinae tribe. Bolton raised the tribe to subfamily status in 2003, suggesting that Agroecomyrmecinae might be the sister taxon to Myrmicinae. It has since been discovered to be one of the earliest lineages of ants, a clade from the basal polytomy for all ants. In 2014, the subfamily was expanded to two tribes. The tribe Ankylomyrmini was moved from the subfamily Myrmicinae to Agroemyrmecinae.
Stigmatomma is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Stigmatomma species are specialized predators. First described by Roger (1859), it was for a long time considered to be a synonym of Amblyopone until it was revived as an independent genus by Yoshimura & Fisher (2012) based on worker mandible morphology.
Mystrium is a rare genus of ants in the subfamily Amblyoponinae. First described by Roger (1862) with the description of the queen of M. mysticum, the genus contains 14 species, all of which occur in the rainforests of the Old World with over half of the species endemic to the Malagasy region.
Xymmer is a genus of ant in the subfamily Amblyoponinae containing the single species Xymmer muticus.
Gaoligongidris is an Asian genus of ants in the subfamily Myrmicinae. It contains the single species Gaoligongidris planodorsa, collected in the Gaoligong Mountains, Yunnan Province, China. The genus is known only from workers and nests in the soil, and forages on the ground. While similar to the genus Lophomyrmex of the tribe Attini, Gaoligongidris is most closely related to the Indo-Australian Lasiomyrma, tribe Crematogastrini.
Furcotanilla is a genus of ants in the subfamily Leptanillinae containing the single species Furcotanilla furcomandibula. The genus is close to Protanilla, from where the type species Protanilla furcomandibula was transferred from by Xu (2012). Its only species is known from Yunnan, China, where it nests in the soil and forages on the ground. Queens and males are unknown.
Stigmatomma pluto is a species of ant in the subfamily Amblyoponinae. The species was first described as Amblyopone pluto by Gotwald and Levieux in 1972 and moved to the genus Stigmatomma in 2012.
Fulakora is a genus of ants in the subfamily Amblyoponinae. The genus has a worldwide distribution, and like most other amblyoponines, Fulakora species are specialized predators. It was originally described as, and for a long time considered to be, a subgenus of Stigmatomma until it was elevated to an independent genus by Ward & Fisher (2016).
Stigmatomma scrobiceps is a species of ant in the genus Stigmatomma. It was described as Bannapone scrobiceps by Guénard et al. in 2013, based on two specimens collected in Yunnan Province, China, and placed as the second species in Bannapone. It was moved to Stigmatomma by Ward & Fisher (2016).
Myrmelachistini is a tribe of ants in the family Formicidae. There are at least 2 genera and 50 described species in Myrmelachistini.
Stigmatomma trigonignathum is a species of ant in the subfamily Amblyoponinae. It is considered one of the rarest ants in the world, only known from one specimen collected in 1948 and another observed in 2008. Both records are from the Piedmont region of North Carolina.
